GeForce GT 240 GDDR5 vs Radeon HD 5970

Intro

The GeForce GT 240 GDDR5 features core speeds of 550 MHz on the GPU, and 850 MHz on the 512 MB of GDDR5 memory. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Compare all of that to the Radeon HD 5970, which features a clock speed of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 256-bit memory bus, and makes use of a 40 nm design. It features 1600 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Difference: 214400 (1218%)

Pixel Rate

The Radeon HD 5970 is much (approximately 2009%) faster with regards to full screen anti-aliasing than the GeForce GT 240 GDDR5, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon HD 5970 92800 Mpixels/sec
GeForce GT 240 GDDR5 4400 Mpixels/sec
Difference: 88400 (2009%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
